1 Pound - Elizabeth II Convoy SL 64, Borgestad

Convoy SL 64 was a slow westbound Atlantic convoy attacked in October 1940 by a wolfpack operating under Admiral Dönitz's expanding tonnage war strategy. The attack — coordinated across multiple nights — resulted in the loss of several vessels and remains one of the grimmer early examples of wolfpack tactics achieving sustained contact with a single convoy. The Borgestad was a Norwegian merchant ship, one of many Norwegian vessels that continued sailing under Allied command after Germany's occupation of Norway in April 1940.

Gibraltar's long-running WWII convoy commemorative program has produced dozens of these silver pound issues, each tied to a specific vessel or action.
